AnAge entry for Hypogeomys antimena

Classification (HAGRID: 02736)

Taxonomy: Kingdom: Animalia
    Phylum: Chordata
        Class: Mammalia (Taxon entry)
            Order: Rodentia
                Family: Nesomyidae
                    Genus: Hypogeomys
Species: Hypogeomys antimena
Common name: Malagasy giant rat

Maximum longevity: 12.6 years (captivity)
Source: ref. 671
Sample size: Small
Data quality: Acceptable
Observations: Males are sexually mature at one year of age but do not normally reproduce until they are two years of age. Females generally stay with parents for two years. In the wild, these animals are capable of reproducing up to 7 years of age [0646]. One captive specimen lived 12.6 years [0671]. The high parental care and long time to maturity partly explain the longer lifespan than that of similar species.
